Is this true or false?

[swanni06]

Hey guys, another member found this and ask me if this web page was true:
http://www.mototuneusa.com/break_in_secrets.htm
I would like you guys to read it and give me your opinion as I have in the past heard breaking in a engine like that is good and some have told me it was a bad idea..

break in?????????? crank a new engine let idle at 2000rpm's till hot, retorque head change oil.. re crank and roll out......... if it's wrong, it will show regardless, if it's right it's right.

His logic in the article is hard to shake. I read the same type break in period written by Smokey Yunick I think. The only problem I see is his statement about modern engines and good tolerances. We're dealing with chinese clones and all the bad reverse engineering that went into them. Need I mention "lead recalls"? I would still think the principles are sound so I'll try it with my new ride. If it doesn't work !Damn! have to rebuild or buy a 4spd KLX. Wish I knew Kevin Cameron or Erv Kanemoto personally. Those 2 I would believe without question. bows_smilie bows_smilie

Ok thanks guys..I didn`t know what to do when I get my x-18..I knew they were below par on the quality scale and I have been told to run any motor when its new like you plan on running it the whole time you own it.I have also been told to be reaaaally easy on it during break-in then run the crap out of it,So I just wanted some expert advice on these as you guys know them like the back of your hand.thumbsup2

The days of being super gentle on break in are long gone. I do take it easier on a new engine than I do later, but mainly I avoid max rpm and try not to load the engine up too much. But hard acceleration up to about 75% max rpm is fine and as he says it's actually good for the engine.

I agree with his statements about oil. I use a quality mineral oil for break in then switch to full synthetic. Be careful of mineral based car engine oils though. Many contain detergents and other additives which could cause clutch problems. I prefer to use a mineral oil made for motorcycle engines with a wet clutch, then I use Shell Helix Ultra synthetic car oil.

ive broken in engines with conventional motorcycle oil and then i switched to Lucas 10w-40 semi-synthetic motorcycle oil. the lucas semi-synthetic is made for racing hi-revving motorcycle engines with wet clutches and is supposed to help the clutch grip better and last longer. ive heard that fully synthetic car oils are bad for wet clutches (they make them slip more and wear faster) so i stick to the semi-synthetic motorcycle oil. ive also broken in engines with the lucas oil and then just changed the oil after a couple of heat cycles with a fresh bottle of lucas semi-synthetic 10w-40 and i really cant tell hardly any difference. i have always taken it a little easy at first, mostly just not redlining it and not loading it up to much. but i only break it in for 2-3hours and then i just ride it like i am going to ride it from then on. that has seemed to work for me.
